Answer:
a₈ = - 10935
Step-by-step explanation:
the nth term of a geometric sequence is
 = a₁
 = a₁ 
where a₁ is the first term and r the common ratio
here a₁ = 5 and r =  =
 =  = - 3 , then
 = - 3 , then
a₈ = 5 ×  = 5 × - 2187 = - 10935
 = 5 × - 2187 = - 10935
 
        
             
        
        
        
3x + 2y + y - 3x = 180
3y = 180
y = 180/3
y = 60
3x = y - 3x
Let y = 60
3x = 60 - 3x
3x + 3x = 60
6x = 60
x = 60/6
x = 10
Answer: x = 10, y = 60
